The reactor comprises the circular iron core (1) with an air gap, a winding coil (2) with taps, an iron filler (3), an adjusting connecting rod (4) and fixing parts (51 and 52). The circular iron core (1) with the air gap is fixed to the fixing parts (51 and 52); the winding coil (2) with taps is wound on the circular iron core (1) with air gap; the iron filler (3) is disposed in the air gap of the circular iron core (1) and fixed to the adjusting connecting rod (4); the adjusting connecting rod (4) is supported by the fixing parts (51 and 52), and rotates relative to the fixing parts (51 and 52) to drive the iron filler (3) to change the filling degree of the air gap of the circular iron core. The reactor is capable of changing inductance in a stepped or continuous manner within a wide range conveniently and rapidly.
Description
Technical field
The present invention relates to the regulable ring-shaped iron-core reactor of a kind of iron-core reactor, particularly inductance.
Background technology
Due to the complexity of electric power system and transient stability thereof, in carrying out theory analysis, must carry out experimental study.Dynamic Simulation Experiments of Power System system is a kind of physical analogy for power system dynamic step response and the research of relevant new equipment, it is set up according to similarity theory, there is the physical model with prototype same physical properties, be practical power systems by a certain percentage relation dwindled, and retain the electric power system duplicate of its physical characteristic.Dynamic power system simulations is mainly made up of analogue means such as simulation generator, analogue transformer, transmission line simulation, simulation shunt reactor, analog filter, simulation loads.
In Dynamic Simulation Experiments of Power System system, needing to use a large amount of inductance is reactor, and these reactors are due to the regular primary equipment that will simulate different parameters, and its inductance value needs regular adjustment.
Existing method is that several taps are set on reactor winding, needs will be connected to different taps while changing inductance value.Its shortcoming is because tap can only arrange limited quantity, and therefore its inductance value can only be selected between a small amount of definite value, cannot realize continuous adjusting, and all needs to remove former tap connecting line rewiring while changing inductance value at every turn, and workload is large.
Traditional air core reactor volume is large, and install in inconvenient laboratory, and it is because its magnetic circuit is air, is also difficult to produce the reactance of large inductance value, even if tap is set, its adjustable range is also limited.
Summary of the invention
The object of this invention is to provide a kind of can fast and easy, on a large scale, classification or continuously change the reactor of inductance value.
Technical scheme of the present invention is: the regulable ring-shaped iron-core reactor of a kind of inductance, comprise: endless belt air gap iron-core, the winding coil with tap, filling iron plate, regulating connecting rod and fixture, endless belt air gap iron-core is fixed on fixture, be wound on the air gap iron-core of endless belt with the winding coil of tap, fill iron plate between the air gap iron-core air gap of endless belt, filling iron plate is fixed on regulating connecting rod, regulating connecting rod is supported by fixture, and drives filling iron plate to change air gap compactedness unshakable in one's determination by regulating connecting rod relative to rotating of fixture.
Above-mentioned endless belt air gap iron-core is laminated and is cut out air gap and makes by ring-shaped silicon steel sheet.
The above-mentioned wire that is surface insulation with tap winding coil is made.
Above-mentioned air gap is filled iron plate and is pressed into by silicon steel sheet stack, and its area is greater than endless belt air gap iron-core sectional area, and thickness is less than the air gap thickness of endless belt air gap iron-core.
Above-mentioned regulating connecting rod and fixture are made up of nonferromagnetic material.
The present invention adopts that volume is little, the linearity good, the low ring iron core reactor of cost, being applicable to being suitable for laboratory installs, the coil tap that can connect by change or change the compactedness of filling iron plate and fill ring-shaped core air gap by rotating regulating connecting rod, just can be on a large scale, classification or continuously change the inductance value of reactor, fast and easy realizes the adjustment of inductance parameters.
